Blowing nozzle and lung secretion discharge device

Abstract

The invention relates to the technical field of lung secretion discharge, and discloses a blowing nozzle and a lung secretion discharge device. The blowing nozzle comprises a blowing nozzle body withan air blowing channel, one port of the air blowing channel is an air inlet, and the other port of the air blowing channel is an air outlet; at least part of the blowing nozzle body forms an oral cavity section allowed to be placed in the mouth by a user, and the outer contour dimension of the oral cavity section changes in the axial direction of the oral cavity section. The outer contour dimension of the oral section changes in the axial direction of the oral section, for example, in the axial direction facing the air inlet, namely, the direction from the air outlet to the air inlet, the outer contour dimension of the oral cavity section is continuously reduced or the outer contour dimension of the oral cavity section is continuously reduced and then continuously increased so that different users, such as adults or children, can select corresponding parts on the oral cavity section according to the sizes of the mouths, and then the blowing nozzle can well adapt to different people groups and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of pulmonary secretion discharge, in particular to a mouthpiece and a secretion discharge device provided with the mouthpiece. Background technique [0002] It is known that healthy human lungs have a natural mucus clearance system. In the lungs of healthy people, the cilia on the tracheal wall vibrate in a single direction at a frequency of 15-25 Hz in a coordinated and rhythmic manner, which dilutes the viscous secretions in the trachea, that is, changes from a viscous state that is not easy to flow to a state that is easy to flow. The thin state of the flow, so the fluidity of the mucus is significantly increased, and can flow with the movement of the cilia, and transported to the throat, and finally discharged from the lungs through coughing or swallowing. [0003] However, in people with weak lungs, lung disease, or other conditions that make the lungs less able to clear themselves, such as reduced mov...

Problems solved by technology

But similarly, the applicant's investigation found that these devices also have certain deficiencies in actual use. For example, the part of these devices that is used for the patient's oral cavity has a single shape and cannot be well adapted to different patients. For example, What is suitable for adults is not suitable for children; for another example, in the device disclosed in patent document CN1310632, although the power supplement device can form a suction effect at the air outlet of the lung vibration device, the device does not vibrate the lungs of the patient. Only these devices work, and patients with the ability to inflate cannot play their own initiative and participate in the process of insufflation, so that the patient with insufflation ability is in a passive state, which is to a certain extent Not beneficial to enhance the therapeutic effect
